TYPEWRTING MACHENE.

Application filed October 26, '19233; Serial No.. 6703825.

This invention relates to kstencil cardholders, and associated ribbon-feeding' mechanism for typewriting machines; that is to say,l to.I means whereby stencil cards may be held to,I the platen and line-spaced over; the same,` while ay ribben for sta-ining, and thereby ren-eleri-ng` visible, the stencil;cuts, is fedV over the platen between the latterI and the stencil card.A n

Ribbons for this purpose are ordinarily ribbons of the breadth of the stencil, fed around the. platen, instead of lengthwise thereof sto as not to be affected by' the movementfo--f the stencil withv the platen in letterfeed and return directions. Heretofore Isuch ribbons have been automatically fed in: one ,direction and. handlwound in the other directionaor, when automatically fed in" one or both-` directions7 have been fed through connections from the platen,A and by line-space feed of the platen. fn the use ofV the: machine for the' stenciling of cards, however; the card-holders may lbe linespace-d withoutv lines-pacingof theJ platen; and this is desirable since it relieves the line-spacing mechanism of the work of turni-ng);l the platen. Nevertheless, the ordi= nary plateneline-spaoing mechanism be employed to line-space the card-holder, through the expedientv of having' connections, from such line-spacing mechanism, to botlirtheA card-holder and: the platen, and dis'- ,connecting such: line-space mechanism from f the' platen when the Card-holder is toy be lused.'l

An object of the pmesent4 invention isA the provision of means, in mechanism of' the general character" mentioned, whereby the ribbon may be: fed automatically inI either direction, at wilhand without moyement of the platen or type-keys.. A A feature. of the invention, inf the 'pre ferred embodiment thereof, a ribbon-feed ing mechanism operable by tliezcardholder in the movements of the latter, incidental to li'neespacing thereef and return of' the same to initial position,v in stenciling' the successive cards.

Ak further feature' of the .invention be: the use of the platen-line-spaeingmeans in effecting feed ofthe ribbon;` preferably by connections from suchI platen-line-spacing means, through the card-holder, to the ribbon-feeding' mechanism,

:in its preferred form,l a feature of the.

invention may reside ina mounting of the iibbondiol'dingdevices. spoolsfor instance, and of the ribbon.-feeding` mechanism,fo-n a card-holder frai^ne,"soA that the same, to;- gether' vwith the card-holder, and without any assembling or disassemblingg,A may,l as aV a platen-frame and associated. parts of a typewriting machine embodyingv the present invention- Figure2 is a toppla-n view of the apparatus shown in Figure 1, 1

Figuref/ is a view, inside elevation, taken on the line 3 3 of Figure l, showin-g the platen and card-holder line-spacing` mech-anisms and ribbon-feeding mechanism; the card-holder being;` in its lowermost or nor,- mal position, and the ribbon-feeding mechanism being shown as functioning on the left-hand ribbon-spool?.

Figure 4: isv a view, in side elevation, on the line if-4i of Figure l, showing the ribbon-feeding mechanism functioning on the. right-hand ribbon-spool.

Figure 5 is a view similar to Figure 3, except that the cardholder line-spacing mechanism is more iufllyV shown, and the card-helder is line-spaced upward from its Figure 3 position.

Figure 6 is a view, in side elevati-on, on the line 6--6 of Figure 2^, showing a crosssection` of the card-holder andshowing the ribbon.

V-The platen l0, which' may be of' meta-l, is l--to an axle 1l journaledl in the side plates i2 of the platen-frame. The platen niej be rotated' by means of the usual fingerwheels 18, or byv means of a line-space ratchet-wheel 111-. The latter may turn freely without movement of the platen, or may be lock-il to the platen-axle to cause the platen to have line-feed rotation when the linespace mechanism is operated. A linger-piece 15. movable in and out longitudinally of the left-hand end of the platen-axle, operates a clutch-device., not shown, for locl-ing the ratchet-wheel to the platen and for releasingl the platen from the line-space mechanism. This clutch-device may be that shown in VTUnited States Letters Patent to Helmond, No. 1.150.366, dated August 17, 1915, and so is not described in detail here. The linespace mechanism for rotating the ratchetwheel 1t, which mav be that found in the Trhiderwood standard typewriting machine, comprises a slide or plunger 17 movable forward and backward on the left-hand framepiece 12 and carrying; a pawl 1S for engagement with the teeth of the ratchet-wheel. A spri fr 19, secured at 2O to the slide 1T and secured at 21 to the side piece 12, acts to hold the slide forward in its normal position and to return it to such position when free to do so. A. line-space lever, in the form of a bell-crank 22 pivoted at L3 to the side piece 12. has one arm 24 thereof disposed for engagen'ient with an offset 25 on the forward end of the slide 1T; so that, when the lever 22 is thrown to the right, the slide is moved back against the action of the spring 19 to effect line-feed of the ratchet-wheel.

As hereinbefore mentioned, the card-holding' device, including all parts thereof and actuating` mechanism therefor. may be affixed as a unit to the platen-frame and removed as unit therefrom, according to the intended use of the machine. It therefore has its own frame-members, which consist of fiat end plates 89 which are tied together bf? a rod 40, adapted to be set upon the usual fiat upper offsets or flanges l1 of the side pieces 12 of the platen-frame.

Journaled in dependingr ears 52 on the side plates 3f) of the card-holder frame is a rockshaft Fast on the rock-shaft 53 are a pair of arms (see Figures 2, 3 and 6), which extend up from the rock-shaft 5S and thence forwardly well above the platen. The forward ends of the arms 54 are turned downward, as at 55. l frame 56, on which the stencil-cards are directljv7 supported, has upturned ears 57 at the ends thereof, by means of which it is pivotally mounted at 5S on the ends 55 of the arms 54 Coilsprings 59, secured at one end to lugs 66 on ears 5T, and at the other end to pins 61 on the arms serve to hold the frame 56 Vin such position that the stencil will properl'v lie against the platen. top-pins 62 on the lugs 60, by engagement with shoulders 63 on the arms 54. determine the desired setting of the stencil-frame with respect to the platen.

The stencil-frame comprises an upper cross-reach 6-l-, having a central upper bend 65 therein to permit of insertion of the operators lingers for placement or 1emoral of a stencil-card. On the cross-reach 6l. at each side thereof, is a forardly-extending ear 66 of the Igeneral curvature of the platen; and secured to the ears 66 are the laterallyprojecting ears 67 of a plate comprising side pieces 68 which extend forward and downward to follow the general cuiw'ature of the platen so as to he set snual)v thereto. At their lov-:er ends the sioe pieces (5S have soldered to the front :tace thereof a thin metal strip 6), which forms a cross-reach and ties together the side pieces 68 into a single plate. rhe side pieces 68, together with the upper cross-reach and the lower cross-reach 69, therefore. form a frame with an opening' therein which is rectangular eucept for the bend 65, for the operators tin- Agers, at the upper portion thereof. The plate forming the lower cross-reach 6) of this frame is turned rezuwardlj.7 around the lower enges of the side pieces 68. and is thence turned upward at 'T0 to form a pocket or seat for the stencil-cards: the upturned lip of this pocket-piece (itl- 7U bein;T spaced sufliciently from the rear fac-,s of the framemembers 68 to permit of easy,- insertion of the stencil-cards therebetween.

stencil-card 80 is shown in position in the Card-holder. This stencil-card comprises a rectangular cardboard frame S1, to the rear of which is pasted the stencilinf; sheet lVhen the card is in position. with its lower edge seated in the pocket 60-'70 and with its side margins in proper position. the steneilinp;` sheet 82 is seen through the cardholder frame 56, (S8- 69, and in position to receive type-impressions. In insert ing the stencil-card, it is passed down iu front of the upper cross-reach 64 of the card-holder frame, and thence down behind the side reaches 68.

It has been stated that the arms of the card-holder are on the rock-shaft This is to permit the card-holder to be hue-spaced upward around the axis of the shaft 52E. The curvature of the card-holder is such as to hold the card properlyY to the platen. between the latter and the usual type-har guide, in any angular position of the arias 54. In Figure 6, the card-holder is shown as having4 been swungI down so that the trinmay write on the upper portion of the latter. The card is shown of such lcnffth that as least five lines may be wri`l en thereo: as the card-holder is progressivelj,` steA or line-spaced upward.

To effect such line-space movement of the card-holder from the platen line-space mia-l anism heretofore described` the foilowiai mechanism is employed. Fast on the sh 53 is a segmental ratchet-plate 96. Loos x nsteaelr ifvote'dA on; the shaft 532 is an armi 97 havmg vpiwote'dl thereto, at its forward end, a p'awvl 98 forengagement with the teeth 99 on the plate 96. A coil-spring 100,. connected to the arm 97 and to the pawl' 98, when free: to doA so., throws the pawl into engagement with.v the. teeth, and holds the same in operative: engagement with the teeth. l/Vhen the arm 9,7 is forced to its lowermost position, however, a dog: 101 on the. pawl, by' engagement with. a pin 1021011 abracket.- 10.3, depending from the side piece 39of the. card-holder frame, causes the pawl to be rocked. and held out. of engagement l with the teeth 99; A. leaf-spring- 10l, bearingf on thez upper edge. of the arm 97 and secured. to a pi'irlO onV the card-holden frame: side. piece: 39, pressesy down the arm 97 to release the pawl 98` from the teeth 99 and to: hold the.` pawl normally out of engagement with' the teeth 99 against the action of the spring 100;y the leaf-spring 104' being sufficiently'stronger than the spring 100 to effect this result.

AThe arm 97,A at its forward end, is turned up at 106, and is thence turned leftward at 107 and downward at 108, to form a` U (see Figures 1 and 53)'. They downturned portion 108 of. this U member (see Figure 3) normally lies in the path of rearward movement. of the offset 25'v on the forward end of the platen' line-space slide 17. This' downturned U- portion 108 has also an inclined or' cam. edgev 109, against which the slide 17 acts when the samev is thrust rearward. It follows that, upon rearward thrust of the slide. 17, on operation of the linespace lever 22, theV arm 97 is rocked upward against the act-ion of the leaf-spring 1011. Thefirst effect of this upward movement is to release the pawl so that it may engage the teeth l99 on the segment-plate 96. Thereupon, thev forcible upward movement of the arm 9-7, by means of the slide 17, causesthe segment-plate 96 tofmove up, and, by means rof the shaft 53 to which it is fast, to correspondingly move up the cardholder. This upward movement will be a one-step linespace movement. Upon release of the linespace lever, the spring 1041 throws the arm 97 back to its normal position; that is to say, into position: for engagement of the pawl 98 with the next succeeding tooth 99- upon the next operation ofthe line-space lever. A springfdetent 110, by engagement with the teeth 99, ma;7 serve to hold the segmentplate 96 and card-holder, against accidental displacement, inthe position to which they have been line-spaced'. After stenciling onv a card has been completed,.and when the stencil-card has been removedl and replaced by another card, the card-holder, together with the segment-plate 96, may be thrust down by meansy of a finger-piece 111 on the seg.- m'enteplate 96,. or by means of finger-pieces 112 on the card-holder-snpporting armsA 54S. The lowermost position of the card-holder may be. determined by engagementgoiif the pin on. the cardholder-frame side'piece:` 39 with the upper end of a: slot 1131in the segmental ratchet-plate 96.. Engagement of pin 105 with the lower end ot the slot 113 may determine the uppermost position. to which the card-holder may be moved.

As line-space movement of.' the pla-ten is unnecessary inthe use of the present inwentionf, the ratchet-wheel 14, as hereinbefore Suggested, may be unlocked from the platen so that opera-tion of the line-space lever 22, to.l line-feed the cardholder, will have no` effect upon the platen. This makes easier the effort of line-spacingthecard-holder, and permits the rear pressure-rolls to bie left in their normal position against the platen..

A ribbon 115 (see FigureV 6) is shownas havingy one end attached to', and wound up on, a spool 116, whence it passes around the platen, and at its other ends is attached to, and woundupon, a spool 117. -The spools 116 and 117 arel jAour-n-aled in plates or brackets 118, set upon' and movableA as a unit with the card-holder frame. 'l-he shaft l10 of the cardlholder frame passes through the brackets 118;: and the latter arey held against lateral outward displacement on the shaft 10 by means of collars 119,y and against displacement towards each other by means of spoolhubs 120'.. rlhe shaft 53 prevents rocking-of the brackets 118' on the shaft 40; and, to this end, the brackets 118 are; slotted at 121 to receive, and rest upon, the shaft 53.

Fixedly connected to theI spools 116. and -1 17 are yratchet-wheels 122 and 123, respectively. (l0-operating` with they ratchet wheels 122 and 123, to effect ribbon-feed rotary movement of' the same',l are pawls' 124 and 125, respectively; these pawls; being pivotall)v7 mounted at 126 andy 127 on a. rockable hand-lever 128, having a handle 1287L on theupper end: thereof. rllhe hand-lever 128, as indicated in Figures 3 and 41, is for the purpose determini-ng upon which of the spools-116 and 117 the ribbon-feeding mechanism shall function; or, in other words, for Adetermining the direction of feed of the ribbon.v ln Figure 3, the leverV 128 is shown as pulled forward to cause the pawl 125 to cohoperalte withv the ratchetwheel 123, the pawl 124, being then disabled; and, in Figure l, the handlever 128 is shown as thrown rearwardl to disable the pawl 125, and toy position the pawl 1.21`- for action on the ratchet 1122. Each of the pawls 124 and 125l is provided with a. tail 129; the tails 129 being connected'by a spring 130r which tends to draw the same together, and therebyv rock the pawls toward the ratchet-wheels. The head 1.31 oli a stud! 132 serves asa stop for both pawls (see 3 and 4); so that the spring 130 cannot 141 from engaffement with the ratchet 123,

throw the pawl, which is intended to be disabled, into engagement with its ratchetwheel, and so that the spring may have a set anchorage to enable it to properly function upon the pawl which is intended to be et'- tective on its ratchet-wheel.

The lever 12S, which supports the pawls, is itsellZ supported and pivotally connected by means ot the stud 132 t0 one arm 134 of a bell-crank lever pivoted at 135 to the right-hand face of the lett-hand bracketplate 11S. rlhe hand-lever 128, on the other hand, is on the lett-hand side of the letthand bracket-plate 118, and, consequently, the stud 132 extends through an opening 136 in this bracket-plate. The other arm 137 ot the aforesaid bell-crank lever is connected by means of a link 13S with the right-hand card-holder arm 54; the connections 139 and 140 or" the link 138 to the arms 137 and respectively, being pins on which the link 138 may freely rock.

It follows from the connections aforesaid that. as the segmental ratchet 96 is fed upward with the card-holder, the link v138 is forced upward from Figure 3 to Figure 5 position, and the bell-crank 134-137 is rocked counterclockwise to cause the pawl 125 (Figures 3 and and 124 (Figure 4) t ride idly over the teeth of the corresponding ratchet, according to which ot the Figures 3 and 4 settings is had. lVhen, however, after stenciling on a card has been completed, the card-holder is thrown down from Figure to Figure 3 position, the link 138 is pulled downward, and the bell-crank 134--137 rocked clockwise to cause the effective one of the pawls 124 or 125 to rotate the corresponding ratchet-wheel and ribbonspool. In other words, the ribbon gets one feed in one or the other direction every time the card-holder is thrown to normal position for commencement of writing on a new stencil.

Dogs or detents 141 may serve to hold the spools against accidental unwinding; and the pin 135. which serves as a pivot for the bell-crank 134-137, may also serve as a support on which these dogs or detents are jivotall)T mounted. A spring 142, which connects the tail-pieces 143 of the detents 141, urges the latter toward the ratchets 123 and 122. Stop-pin 145, when engaged by the detents 141, holds the latter out of engagement with the ratchet-wheels. In Figure 3. the stop 145 is shown as holding one detent 141 from the ratchet 122, so that the spool 116 may rotate to permit the ribbon to be drawn therefrom while the spool 117 is being ted to pick up the ribbon; the other detent 141 at this time being in engagement with the ratchet 123 to hold the latter after feed thereof. In Figure 4, on the other hand, the stop-pin 145 is holding one detent while the other detent 141 engages with the ratchet 122, for feed ot the ribbon in the opposite direction. The stop 145 when engaged by one ot' the detents also acts as an anchorage vlor the spring to cause the latter to act effectively in holding the other detent in operative position.

Since the paw]-carrying and setting lever 23 is itself bodi y swung between Figure 3 nd Finire 4 positions with the bell-crank 34-137, and, since the pivot-pin 132 of this lever 123 passes through the brarket-plate 1.18, the hole 13G, through which the pin 132 asscs, is elongated as shown in Figure 3. The pawl-setting lever 12S carries a pin 146, means ot which it may be held in either Figure 3 or Figure 4 position. For this purpose. the pin 146, in Figure 3 position ot the lever 128, engages a shoulder 147, and, in Figure -lf position ot the lever 12S, a shoulder 143 on a stop-arm 149. This arm 149 conveniently loosely pivoted on the pin 139 which connects the bell-crank arm 37 and the link 138 at the upper end ot the te The other end of the arm 140 has an 1 oi'fset therefrom, to which is cone one end ot a. spring 152, the other end the pring- 152 being connected to a piu 3 on h bracket 11S. rl`he spring 152 exa downward pull on the stop-arm 149. -tvfeen the shoulders 147 and 14S on the m 149, the latter is bellied outward, as shown at 154, to form a. cam-surface, by means ot which the pin 14() is held to whichever the stops 147 and 14S it may be brought; and by means of which the stoparm 149 may be cammed upward against the resistaiice ot the spring 152 to permit movementI oit the hand-lever 123 between Figures 3 and 4 positions.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
